A. GENERAL (WITH BOILER IN USE)
General boiler observation can be performed by the
owner. If any potential problems are found, a qualified
installer or service technician/agency must be notified.
1. Remove any combustible materials, gasoline and
other flammable liquids and substances that generate
flammable vapors from the area where the boiler is
contained.
2. Observe general boiler conditions (unusual noises,
vibrations, etc.)
3. Observe operating temperature and pressure on the
combination gauge located in the supply piping on
the left side of the boiler. Boiler pressure should
never be higher than 5 psi below the rating shown
on the safety relief valve (25 psig maximum for a 30
psig rating). Boiler temperature should never be
higher than 240° F.
4. Check for water leaks in boiler and system piping.
5. Smell around the appliance area for gas. If you smell
gas, follow the procedure listed in the Lighting
Operating Instructions to shut down appliance in
Section 7, Start-Up Procedure Part B.
B. WEEKLY (WITH BOILER IN USE)
1. Flush float-type low-water cut-off (if used) to remove
sediment from the float bowl as stated in the
manufacturer’s instructions.
C. ANNUALLY (BEFORE START OF
HEATING SEASON)
1. Check boiler room floor drains for proper
functioning.
2. Check function of the safety relief valve by
performing the following test:
a. Check valve piping to determine that it is
properly installed and supported.
b. Check boiler operating temperature and pressure.
c. Lift the try lever on the safety relief valve to the
full open position and hold it for at least five
seconds or until clean water is discharged.
d. Release the try lever and allow the valve to close.
If the valve leaks, operate the lever two or three
times to clear the valve seat of foreign matter. It
may take some time to determine if the valve has
shut completely.
e. If the valve continues to leak, it must be replaced
before the boiler is returned to operation.
f. Check that operating pressure and temperature
have returned to normal.
g. Check again to confirm that valve has closed
completely and is not leaking.
3. Test low-water cut-off (if used) as described by the
manufacturer.
4. Test limit as described in Section 7, Part C, “Check-
Out Procedure”.
5. Test function of ignition system safety shut-off
features as described in Section 7, Part C, “Check-
Out Procedure”.
6. Remove the top/front jacket panel and inspect for
any foreign debris that may have entered through air
inlet vent.
7. Inspect burner for deterioration. Replace if necessary.
8. With boiler in operation check that condensate is
dripping from drain hose. Check for any restriction in
condensate drain line.
a. CONDENSATE CLEANING INSTRUCTIONS:
1. Turn the thermostat down or off so the
Pinnacle will not cycle and then follow the
steps below.
a. Close manual gas shutoff valve.
b. Disconnect the condensate piping from the
outside connection (not from the Pinnacle)
so flow can be observed.
c. Block the air flow in the exhaust by
temporarily plugging the exhaust from the
outside vent.
9. MAINTENANCE
The following annual inspection must be performed
by a qualified service technician.
CAUTION
When servicing or replacing components, be
absolutely certain that the following conditions are
met:
● ● Water, gas and electricity are off.
● ● The boiler is at room temperature.
● ● There is no pressure in the boiler.
